            Note: A total of 64 base address settings are available. The
            switches are a binary representation of the decimal memory
            addresses. S1/6 is the Most Significant Bit and switch S1/1
            is the Least Significant Bit. The switches have the following
            decimal values: S1/6=512, S1/5=256, S1/4=128, S1/3=64,
            S1/2=32, S1/1=16. Turn off the switches and add the values of
            the switches that are off to obtain the correct memory
            address. (Off=1, On=0)
